NightKiller Fanfiction (Title a WiP.....)

Chapter 00

Dodge, you fool!

The battered skeleton's thoughts screamed commands at him, ordering his body to twist left and right, dodging blast after blast. His glowing, sharp red blade lay just feet away from his feet. The skeleton slid to the left, avoiding another red blast. The snow was blasted up from the ground, plowed up in a large mass behind him.

Sharp red bones immediately flew at Killer, who quickly dropped down onto the snow beneath him. A harsh rip sounded on Killer's right, as he glanced to find—

Incoming.

The skeleton rolled over, a series of jagged bones lodged into the snow in his place.
Killer jumped up, then crouched low. He eyed Fell with that crazed expression, liquid hate pouring out of his empty black sockets. The other Sans, commonly known as Fell, sweat with effort and exhaustion. The other's magic was obviously running low. It was displayed on his sweaty face. Killer saw hints of fear in Fell's eye, he knew what was hidden behind that forced smile.

Darting to his right, Killer headed straight towards his knife. He himself hadn't used much magic yet, Fell had to lose. Ignoring the multiple amounts of blasts sounding behind him, Killer snatched up his red knife and made a sharp turn- sprinting at his victim.
Fell, freaking out, wrinkled his face up in a snarl and summoned a new gaster blaster. A huge one that loomed over the two monsters, hovering right above Fell and pointed directly at Killer.

Killer skidded to a halt, grinning up widely at Fell's newly summoned weapon.

"Now, that's not very fair,"

The skeleton snickered, gripping his knife.

"You shouldn't have come 'ere, freak!"

The other barked, sweat pouring down his skull. Fell's soul beat fast and hard, threatening to practically pound out of his chest. Killer ignored Fell, though tilting his skull down to meet the other's gaze coldly. Then, out of nowhere, Killer leaped. The first thing he heard was the familiar, loud noise of a blast being fired. Killer went deaf for a brief moment before realizing that he had collided with Fell, who stared up wide-eyed in fear at his attacker. The skeleton was hopeless. His magic was nearly drained, and he felt like passing out. Killer had the advantage. Truthfully, he did at the start.

Killer raised his hand high with that maniacal grin, his knife directed right at Fell's chest.

"This universe has no need for scumbags like you."

The murderer cooed, striking down his kni—
Killer was immediately lifted up off of Fell, a black, gooey tentacle wrapping around his waist. Fell inhaled sharply, teleporting away. Lucky bastard would pass out the moment he made it to his destination.

"That is enough, Killer."

Spoke a familiar voice. Killer instantly dropped his knife, looking down. As if he expected to see anything there but his fallen weapon. The tentacle's grip on him increased, squeezing him.

"Ah, you're here."

The murderer snickered in Nightmare's grasp. The slimy tentacle then turned Killer around so that he was faced with his superior's sadistic grin.

"I told you specifically not to kill anyone here."
He spoke calmly.

"He won't be missed, I almost had 'em!"

Killer snapped. His poor knife hadn't had the satisfaction of slicing into bone, or even flesh, in years. And sadly, it would never have the treat of slicing into a certain someone's goop.

"We're leaving. Now."

The taller, goopy skeleton declared with a twitch of his tentacles. Then, without waiting for Killer to protest, he summoned a portal and practically tossed the other into it. Casually walking through afterward. Obviously, the portal led to Nightmare's grand castle, where else would he be traveling? This was not only the headquarters but his home.

Killer landed with an oof, sliding across the shiny black floor. His skull bumped into some counter, which earned a loud groan from him. There weren't even any maids present in the huge building, it's ridiculous how well-kept everything was.

The skeleton rolled over and then got to his feet, brushing snow off of his shorts before facing Nightmare. They had gone to Underfell simply to cause some trouble. Apparently Killer failed that mission by trying to get rid of Fell permanently. Why did Nightmare even care?- it was just one little timeline.

The drippy skeleton approached Killer, who stood his ground with an unpleasant glare. Nightmare reached inside his pocket, causing Killer to tense up but- what Nightmare pulled out was simply Killer's knife.

"You left this. Be more careful next time."

He handed him the knife before melting down into a black puddle, reappearing at Asgore knows where. The murderer just stood there, knife in hand. No punishment?

"...Weirdo. Fuck- I hate this job."
